A Japanese computer has earned the number one spot on the Top 500 supercomputer list, ending China’s short reign of just six months. At 8.16 petaflops (quadrillion floating-point calculations per second), the K computer is more powerful than the next five systems combined.
The K computer’s performance was measured using 68,544 SPARC64 VIIIfx CPUs each with eight cores, for a total of 548,352 cores, almost twice as many as any other system on the Top500 list. The computer is still being put together, and when it enters service in November 2012 will have more than 80,000 SPARC64 VIIIfx CPUs according to its manufacturer, Fujitsu.
Japan’s ascension to the top means that the Chinese Tianhe-1A supercomputer, which took the number 1 position in November last year, is now in second spot with its 2.57 petaflops. But China continues to grow the number of systems it has on the list, up from 42 to 62 systems. The change at the top also means that Jaguar, built for the U.S. Department of Energy (DOE), is bumped down to third place.

Yahoo wants to aid in smartphone owners finding mobile applications and information about them.
On Thursday, the company is debuting a feature in its search engine called App Search, as well as application search tools for Android and iPhone devices named AppSpot.
Both the new App search feature and the mobile search tools can be used to seek applications for iPhone and Android devices, although the company expects to expand that scope in the future.
For now, Yahoo has indexed the mobile application catalogue of the Android Market and of the Apple App Store, and is convinced that it can do a better job than the search tools of those two online shops.
Finding information about mobile applications, like descriptions, ratings, reviews and recommendations, is at a rudimentary stage similar to web search in the mid-1990s, Seth said.
The way Yahoo sees it, many people today struggle to find the right mobile application among the hundreds of thousands available for Android and iPhone devices.

The U.S. State Department questioned the Chinese government regarding an attack that had temporarily shut down the website Change.org after the site hosted a petition urging Chinese authorities to release artist Ai Weiwei from custody.
U.S. deputy assistant secretary Daniel Baer raised concerns about the attack in April with China’s foreign ministry, according to an official letter sent from the State Department to U.S. Rep. Rosa DeLauro (D-Conn.). Change.org obtained a copy of the letter and released it Tuesday.
The nature of those talks is still somewhat vague. The U.S. Embassy in Beijing said it had no current information on the matter and deferred to the State Department. China’s foreign ministry has yet to respond to a request for comment.
Change.org, an online petitioning platform, was the victim of a distributed denial of service (DDoS) attack originating from China on April 17. The attacks nearly brought down the site for days.
DDoS attacks can do this by using hundreds or thousands of hacked computers to drive traffic to a website. The data will become so overwhelming that the site will become inaccessible to users.
Change.org said the DDoS attacks from China continue to bring down the site intermittently. The FBI is investigating the case, said Benjamin Joffe-Walt, an editor with Change.org.

Apple’s iPhone is moving closer and closer to Nokia’s top spot in smartphones globally, according to first-quarter 2011 results reported by IDC on Thursday.
With the iPhone in the second spot, BlackBerry maker Research In Motion dropped to third after finishing second a year ago, IDC said. 99.6 million smartphones shipped in the first quarter, out of 372 million mobile phones overall.
Nokia sold 24.2 million smartphones in the first quarter, holding on to its global smartphone lead despite announcing that it will move from Symbian to Windows Phone as its main smartphone operating system in next few years, IDC said. Nokia “may find itself in danger of ceding market share as the competition ramps up,” IDC said.
Apple shipped 18.7 million iPhones in the first quarter, IDC said, a new record for a single quarter, “and inched closer to market leader Nokia, with fewer than 6 million units separating the two companies,” IDC noted.
Apple also had triple-digit growth in the U.S., with the Verizon Wireless CDMA iPhone 4, and in greater China.
RIM, while down from second place where it was a year ago, remained in third place from the fourth quarter of 2010. The majority of RIM’s shipments are older, lower-cost devices, IDC noted, a trend that will continue in the second quarter.
Samsung finished fourth in smartphones for the first quarter, with 10.8 million smartphones shipped, while HTC finished fifth, with 8.9 million shipped.
Samsung grew the most of any vendor for the first quarter — 350% year-over-year. Samsung has a multiple-OS strategy and sells mostly Android smartphones, including Galaxy S phones, as well as Windows Phone 7 and Wave devices.

Apple’s next-generation iPhone will have a faster processor and will start shipping in September, several sources with direct knowledge of the company’s supply chain said.
The production of the new iPhone will start in July/August and the smartphone will look very similar to the current iPhone 4, one of the sources said on Wednesday.
The iPhone -debuted in 2007 with the touchscreen, on-demand application template now adopted by its rivals- remains the gold standard in the booming smartphone market.
Reports on the timeline of the new iPhone launch vary, though it is largely expected that Apple will likely refresh its iPhone 4 later this year.
The sources declined to be identified because the plans for the new iPhone were not yet public. An Apple spokeswoman in Hong Kong was not available for comment.
The iPhone is one of Apple’s most successful products, with more than 16 million sold in the last quarter of 2010 and the product accounted for more than a third of the company’s sales in the quarter.
The current iPhone 4 was launched by Apple Chief Executive Steve Jobs in June last year and began shipping the same month in 2010.

Android will be the operating system of choice for 45% of smartphones shipped by the year 2016. It will take up most of the market share vacated by the soon-to-be exiting of Nokia’s Symbian operating system, according to figures released today by ABI Research.
Although Android will come to be the dominant player in the smartphone market, this doesn’t mean that OSes will necessarily see a big cut in their own market shares, ABI said.
In fact, the firm projects that Apple’s iOS will see its market share rise from 16% in 2010 to 19% in 2016, while Research In Motion’s BlackBerry OS is expected to fall slightly from 16% in 2010 to 14% in 2016. Microsoft’s Windows Phone 7 and Samsung’s Bada will also be players in the 2016 smartphone market, as ABI projects those two operating systems to take 10% and 7%, respectively.
ABI vice president Kevin Burden says that although RIM stands to lose a bit between now and 2016, the company will carve a comfortable niche for itself in the enterprise market, as enterprise users will still need the security provided by RIM’s network operations center.
“RIM’s slight loss of share doesn’t mean falling shipments,” he says. “RIM has found its niche, but the consumer market will grow faster than its portion of it.”

American Express has just debuted a digital payment and commerce service that makes it possible to use Android-based devices and Apple iPhones for person-to-person online payments. Visa announced a similar personal payment product in the U.S. on March 16.
Analysts say the moves by Visa and American Express are clearly aimed at challenging PayPal in the personal payments business.
The new Amex service, named Serve, allows consumers and small businesses to make purchases and person-to-person payments on iOS- and Android-based devices. Serve accounts are also accessible on personal computers through Facebook and at Serve.com.
Serve also allows users to create and manage sub-accounts for friends and family members.

Google is joining Citigroup and Mastercard to establish a mobile payment system that will turn Android phones into a kind of electronic wallet, the Wall Street Journal said, citing people familiar with the matter.
The new system, which is in its early stages, will allow consumers to wave their Android phones in front of a small reader at the checkout counter to make payments, the Journal reported.

Motorola Mobility has snagged a number of experienced mobile and Web engineers from Apple and Adobe and is developing a Web-based mobile operating system as a potential alternative to Google’s Android software, according to a source familiar with the matter.
Asked to comment, Motorola did not refute the existence of the project but continues to affirm its interest in Android. “Motorola Mobility is committed to Android as an operating system,” a company spokesperson stated.
Jonathan Goldberg, an analyst with Deutsche Bank in San Francisco, said that he too had heard Motorola was at work on its own operating system. “I know they’re working on it,” “I think the company recognizes that they need to differentiate and they need options, just in case. Nobody wants to rely on a single supplier.”
